His alleged accomplice, 38-year-old Michael Ginnietti of Winthrop, was arraigned Monday afternoon in Lynn District Court. He pleaded not guilty to ten charges related to the armed robbery.

He was ordered held without bail pending a dangerousness hearing on Friday.

At Ginnietti’s arraignment, prosecutors said the robbers wore plastic masks and bullet-proof vests as they stole $5,200 from the Saugus Bank on Lynn Fells Parkway late Friday afternoon. One of the men was also wearing an FBI hat.
